Warning- This is about to be the laziest project idea post, as I didn't make this one! Ha hah.
I acquired this boring bar holder with my recent lathe purchase. It is such a cool idea, new to ME at least, I wanted to share it here. It looks pretty easy to make at home.

As you can see, the two "V"s bring any size bar right up to center. All you have to to is turn it so the tool tip is centered. And you can automate this as well by marking them, but that is for another thread.
It consists of a main post, which also allows the boring bar to pass through, therefore determining the capacity:

The pin in the top next to the mount bolt is important to keep the body of the holder aligned with the Main post. That pin fits into the body next to the main bolt:

This part might need multiple parts (3?) to be assembled is the V-clamp, since it would waste a lot of metal to cut metal away- unless you can cast:
... One way to make this tool sort of "indexable" would be to make this U part with FLATs at the clamping end instead of the small "V"s.
Then clamp the boring bars you want to use in place, blue the two flats on the clamp, and then mill flat areas on the boring bars at the corresponding marks. Does that make sense?

I wish I could read the tag, but it is warn off- I am trying to analyze this pic in Photoshop to help determine the original manufacturer:
All I can make out is a "CLA..." on the top left.
I will be happy to take any measurements or answer any questions if there is any interest!
